EXILL—a high-efficiency, high-resolution setup for $\gamma$-spectroscopy at an intense cold neutron beam facility
/ Jentschel, M (Laue-Langevin Inst.) ; Blanc, A (Laue-Langevin Inst.) ; de France, G (GANIL) ; Köster, U (Laue-Langevin Inst.) ; Leoni, S (Milan U.) ; Mutti, P (Laue-Langevin Inst.) ; Simpson, G (LPSC, Grenoble) ; Soldner, T (Laue-Langevin Inst.) ; Ur, C (Padua U. ; Bucharest, IFIN-HH) ; Urban, W (Laue-Langevin Inst. ; Warsaw U.) et al.
In the EXILL campaign a highly efficient array of high purity germanium (HPGe) detectors was operated at the cold neutron beam facility PF1B of the Institut Laue-Langevin (ILL) to carry out nuclear structure studies, via measurements of γ-rays following neutron-induced capture and fission reactions. The setup consisted of a collimation system producing a pencil beam with a thermal capture equivalent flux of about 10(8) n s(−)(1)cm(−)(2) at the target position and negligible neutron halo. [...]

Lifetimes and shape-coexisting states of $^{99}Zr$
/ Spagnoletti, P (West Scotland U.) ; Simpson, G (LPSC, Grenoble) ; Kisyov, S (Bucharest, IFIN-HH) ; Bucurescu, D (Bucharest, IFIN-HH) ; Régis, J M (Cologne U.) ; Saed-Samii, N (Cologne U.) ; Blanc, A (Laue-Langevin Inst.) ; Jentschel, M (Laue-Langevin Inst.) ; Köster, U (Laue-Langevin Inst.) ; Mutti, P (Laue-Langevin Inst.) et al.
Lifetimes of intermediate-spin states in two rotational bands of $^{99}Zr$ have been measured. These states were populated following the neutron-induced fission of $^{235}U$ at the PF1B beamline of the Institut Laue-Langevin, Grenoble, during the EXILL-FATIMA campaign. [...]

Low-energy Coulomb excitation of neutron-rich zinc isotopes
/ Van de Walle, J (Leuven U. ; CERN) ; Aksouh, F (Leuven U. ; SPhN, DAPNIA, Saclay) ; Behrens, T (Munich, Tech. U.) ; Bildstein, V (Munich, Tech.

At the radioactive ion beam facility REX-ISOLDE, neutron-rich zinc isotopes were investigated using low-energy Coulomb excitation. These experiments have resulted in B(E2,20) values in 74-80Zn, B(E2,42) values in 74,76Zn and the determination of the energy of the first excited 2 states in 78,80Zn. [...]

Lifetime measurements in $^{52,54}$Ti to study shell evolution toward $N=32$
/ AGATA Collaboration
Lifetimes of the excited states in the neutron-rich Ti52,54 nuclei, produced in a multinucleon-transfer reaction, were measured by employing the Cologne plunger device and the recoil-distance Doppler-shift method. The experiment was performed at the Grand Accélérateur National d'Ions Lourds facility by using the Advanced Gamma Tracking Array for the γ-ray detection, coupled to the large-acceptance variable mode spectrometer for an event-by-event particle identification.

$β$ decay studies of n-rich Cs isotopes with the ISOLDE Decay Station

Neutron-rich Ba isotopes are expected to exhibit octupolar correlations, reaching their maximum in isotopes around mass A = 146. The odd-A neutron-rich members of this isotopic chain show typical patterns related to non-axially symmetric shapes, which are however less marked compared to even-A ones, pointing to a major contribution from vibrations.

/IDS
The occurrence of octupolar shapes in the Ba isotopic chain was recently established experimentally up to $N=90$. To further extend the systematics, the evolution of shapes in the most neutron-rich members of the $Z=56$ isotopic chain accessible at present, $^{148,150}$Ba, has been studied via $\beta$ decay at the ISOLDE Decay Station.
